I found that the drama from network "viu" are mistakenly tagged as "viuTV". Though they are both owned by the Hong Kong-based company PCCW and share similar logos, they are two different brands operating separately and should be separated in the listing.
"viuTV" (viu.tv) is a Hong Kong free-to-air television network which mainly produces Cantonese drama and variety shows.
"viu" (viu.com) is a OTT platform available in various markets including Hong Kong, Singapore, Thailand etc. The OTT platform provides drama and show from other production companies and also produces their own drama with the brand "viu original".
Please check this list: mydramalist.com/search?adv=titles&nt=104 . Only shows produced in Hong Kong should be tagged as "viuTV" while the others should be changed to "viu". One exception is mydramalist.com/743503-lovesignal which is produced by Hong Kong "viu original" and should be labelled as "viu".
